I had a SL and it was one of the best boards I've ever owned. Fun, versatile, fast, and never let me down. That said, the Heritage has been my go-to board the most the last couple seasons, but that's because of the terrain I ride. If you want to have 2 boards, the Heritage will provide more contrast. Another option is to get the SL and recoup a few bucks by selling the Evo. The SL can do it all.
